DataBridge Serial Multiplexer (SDR-MUX) User's Manual

DataBridge Serial Multiplexer (SDR-MUX) User's Manual Revision 1.0 1 May 2000

1 Getting Started 1.1 Getting Started To get started you will need the DataBridge SDR, SDR-ACDC power supply, serial cables, the Omega D1132 modules, the RS-422 meteorological station, a computer with a free serial port, and terminal emulation software. Details of the following procedure can found in the DataBridge SDR User s Manual and in Sections 1.2-1.4. 1. Connect the serial cable to a terminal or computer running terminal software, connect the power and serial cables to the SDR, and verify that you see the SDR s main menu. See Section 1.4 of the DataBridge SDR User s Manual if you have any trouble. 2. Connect the meteorological station and Omega D1132 modules to the RS-422/485 ports. Be sure to maintain the proper polarity of the Data+ and Data- signals. Figure 1.1.1 shows how these devices should be connected to the SDR rear panel. Power supplies and the RS-232 serial cable have been omitted for clarity. 3. To verify data is being received, enter serial passthrough mode from the SDR main menu to talk to the SDR-MUX. From the SDR-MUX main menu, type T to test the script interactively, and begin monitoring the data flow. At this point, the incoming data should be displayed on the screen. The data LED on the SDR s front panel should also flash when data is being received. If the data looks correct, everything is connected 3

Typing the serial passthrough escape sequence, +++, will return you to the SDR main menu. 4. To record data (i.e. enter record mode), type R from the SDR main menu or press the record button on the SDR s front panel. The SDR is preconfigured to send an R to the SDR-MUX when entering record mode, which will automatically start the SDR-MUX script. When recording has stopped (i.e. when entering stop mode), the SDR will send a Q, which will halt script execution. SCSI Port SDR Config.

SDR-MUX User s Manual rev 1.0 Getting Started 1.2 Description The DataBridge SDR Serial Multiplexer (SDR-MUX) is an add-on board for the base DataBridge SDR system that is designed to multiplex two input serial ports onto the SDR s single data port. The SDR-MUX is housed in the SDR enclosure and receives its power from the SDR circuit board. The SDR-MUX is equipped with four serial ports: one RS-232 port (Port 0) that is connected internally to the standard data port on the SDR circuit board, one auxiliary RS-232 port (Port 1) that is routed through the rear panel serial port connector, and two isolated half-duplex RS-422/485 ports (Ports 2 and 3) for incoming data. The auxiliary port can be used by your script for monitoring and data routing functions [see Section 2]. Port 0: baud rate 0 Port 0: baud rate 1 Port 0: baud rate 2 Port 0: RTS/CTS handshake enable Port 2 RS-422/485 (half duplex) Port 1 RS-232 (DTE) Port 0 RS-232 (DCE) Port 3 RS-422/485 (half duplex) Figure 1.2.1. The serial multiplexer (SER-MUX) circuit board. The SDR-MUX s behavior is controlled by a script that is loaded and executed by the SDR-MUX. This allows the SDR-MUX to adapt to a number of data recording configurations. For most applications, the SDR- MUX is shipped pre-configured. See the following sections for details on the configuration and editing of scripts, and for details about serial port configuration. 5

Modifying variable names. 1.3.4 Uploading a new script To upload a new script, type U from the edit script menu. Since this operation will overwrite the current script, the SDR-MUX prompts for confirmation of the upload (Figure 1.3.9). If you are sure you want to upload a new script, type Y and ASCII upload your new script using your terminal emulation software. If you cancel the upload from your terminal software you may need to power cycle the SDR-MUX so you can upload a script again. You can escape before you begin the upload by typing any 9

If uploading is cancelled, reset the SDR-MUX. Press Y to continue or any other key to cancel upload... Figure 1.3.9. Beginning an ASCII upload of a new script. 1.3.5 Testing the current script Typing T from the SDR-MUX main menu allows you to run the current script and display the SDR-MUX output in real time. When entering this mode the SDR-MUX will look for a stop action and, if it finds one, will remind you what it is so you can stop the script and exit interactive testing mode. This is important because a script will run indefinitely without a stop action (i.e. the SDR-MUX would have to be power cycled to stop the script). If, by some chance, a script was uploaded that did not have a stop action, the SDR-MUX will warn you and not run the script. Press any key to start the script. The current script's primary stop instruction is: If data from DataBridge Port is "Q" then Stop script and return to menu mode Press any key to run the script interactively... Figure 1.3.10. Testing a script interactively. Notice that the SDR- MUX reminds you what the primary stop instruction is. 10

2 Scripting Reference 2.1 Introduction Scripting allows you to modify the SDR-MUX behavior to suit a specific application. This section will attempt to give the reader some understanding of how to write, compile, and upload scripts for the SDR-MUX. Currently there are no software tools to assist in writing and compiling scripts, as scripts were originally intended for in-house use only. We have decided to allow access to scripting as a service to our customers. 11

SDR-MUX User s Manual rev 1.0 Scripting Reference Each label and opcode+operand occupy a 16 byte record which is represented by the decimal value of each byte delimited by commas. Any unused bytes are set to zero. Characters are represented by the decimal value of their ASCII code. Comments can be added to the right of the script data. The SDR-MUX parses all numbers, so there can be no numbers in the comments. If a number must be represented in a comment, use the word, not the numeral (e.g. 2 must be "two"). 65, 114,109,121,95, 76, 83, 46, 109,117,120,0, 0, 0, 0, 0 // Army_LS.mux 68, 97, 116,97, 66, 114,105,100,103,101,32, 80, 111,114,116,0 // DataBridge Port 65, 117,120,32, 80, 111,114,116,0, 0, 0, 0, 0, 0, 0, 0 // Aux Port 77, 101,116,83, 116,97, 116,105,111,110,32, 80, 111,114,116,0 // MetStation Port 79, 109,101,103,97, 66, 117,115,32, 80, 111,114,116,0, 0, 0 // OmegaBus Port 79, 109,101,103,97, 66, 117,115,95, 65, 100,100,114,0, 0, 0 // OmegaBus_Addr 116,105,109,101,32, 99, 111,117,110,116,101,114,0, 0, 0, 0 // time counter 108,105,110,101,32, 99, 111,117,110,116,101,114,0, 0, 0, 0 // line counter 107,0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // k 130,10, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // if data from port two is <LF> 66, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // add one to variable two 32, 76, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send "L" via port zero 80, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send variable two via port zero 32, 32, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send " " via port zero 96, 5, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // delay five ms 16, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send port two's buffer via port zero 56, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // set variable zero to one (sixteen-bit argument) 35, 35, 48, 82, 68, 13, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send #(one)rd<cr> via port three 96, 50, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // delay fifty ms 32, 76, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send "L" via port zero 80, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send variable two via port zero 32, 32, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send " " via port zero 16, 3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send port three's buffer via port zero 32, 10, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send <LF> via port zero 168,1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // if variable zero equals one (sixteen-bit compare) 56, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // set variable zero to zero (sixteen-bit set) 35, 35, 49, 82, 68, 13, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send #(one)rd<cr> via port three 96, 50, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // delay fifty ms 32, 76, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send "L" via port zero 80, 2, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send variable two via port zero 32, 32, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send " " via port zero 16, 3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send port three's buffer via port zero 32, 10, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // send <LF> via port zero 128,81, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // if data from port zero is "Q" 104,0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // stop the script 128,27, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // if data from port zero is ESC 104,0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // stop the script 128,3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // if data from port zero is CTRL-C 104,0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 // stop the script 0, The name of the current script.
